COMBINED CABLE CLfxl/IP AND WIRE HOLDER.

i ,mareo Application flied July is,

To @ZZ 1e/wm t may concern.'

Be it known that l JOHN A. Liann. dr., a citizen oi' the United States, residing` at Kansas (lity, in the county of Jackson. State oit lvlissouri, have invent-cd certain new and useful Improvements in Combined Cable Clamps and `Wire Holders, of which the follouf'ing is a full and eXact specification.

The present invention relates to devices for supporting electric cables or conduits and the like from the walls or ceilings ot buildings or other supporting structures, and one ot the objects in view is to provide an mprm'ed means of securing` cables oi. this character in position, and especially adapted tor telephone work, where. an auxiliary wire holder is required for suspendingI the branch or bridle wires leading off trom the main cable or conduit.

Incarrying out the invention I have provided an improved cable gripping device with whichis associated an auxiliary wire holder adapted to support the branch wire and also to clamp the cable gripping; device in its proper position.

It is also sought to devise a novel form of adjustable clamping' or supporting` member which is adapted to be readily and conveniently adjusted for accommodating the same to cables or lconduits of varying sizes.

A further object is to provide an eX- tremely simple and compact construction which may be manufactured at a minimum of expense.

`With these general objects in view the invention will now be described with reference to the accompanying drawing illustrating a suitable form of construction which has been devised for embodying the improvements, after which the novel features therein will be set forth and defined in the appended claims.

In the drawingl i Figure 1 is a front elevation showing a portion of the face of a wall having a device embodyingthe present improvements applied thereto, witlr a cable and branch wire represented in broken lines;

Figure 2 is a vertical section, taken on the line 2-2 of Figure 1;

Figure 3 is a front view of the device, shown adjusted to fit a cable of larger diameter 5 Figure l is a perspective view, on. larger Specification of Letters Patent.

scale9 showing` a modified form of cable cl ampi n g iember and Figure 5 is a vertical sectional view of the same.

Referring' to the drawing .in detail, and .more particularly to Figures 1 to 3, the ca ble clamping member is shown as constructed of a single piece of wire which is suitably bent upon itself to form a body portion 6 adapted to be placed in engagement with the tace of a wall 8, the remaining or terminal portions oit the wire being Curved to toria tlexible lingers 10 adapted to grip a cable Wvith this construction said fin-V `fers 10 may be quickly and conveniently spread more or less to .tit over dierent sizes of cables 12, Figure 1 representing the device with the ng'ers spread to grip a cable of relatively small diameter and Figure 3 show in t-he fingers pulled together to grip a cable of the maximum size for which the same are adapted.

Through the eye 14 at the lower end of the body portion 6 of the cable clamping member is passed the shank oi a wire holder which comprises an outer wire receiving; coil 16 of slightly more than one complete turn or convolution, the free terminal of which may be spread. as illustrated in Figures 1 and to provide an opening or passage 18 suliicient for the insertion of a branch or bridle wire 20% leading` oil from the cable 12. The shank 22 of the wire holder is threaded to t into the correspondingly threaded bore or an anchoring' plug or sleeve 24 which' is embedded in the wall 8, the drawing` (Fg ures 1 and 2) showing' said anchoring plug or sleeve embedded in one of the mortar courses 26 of the wall, the outer end or' the plug coming flush with the outer surface of the wall. By this means the cable clamping member may be clamped into secure en* gagement with the face of the wall and the outer end of the plug or sleeve 24 by the action of the wire holder, and preferably I employ a collar 28 on the outer end of the shank next to the coil portion 16 for engagement with the eye 14 so as to space the coil portion 1G away from the Wall and out of engagement with the cable clamping member and thereby leave the terminal portion of the coil free to move and allow the same to be readily spread in inserting the wire 20.

In Figures 4 and 5 are illustrated a medie fication in Which the cable clamping member is simply constructed of sheet metal oomprising the body or Wall engaging portion 6 and the cable gripping portion l0', which modified form of construction may be preferred where a cable or conduit of uniform size is met With and no Vadjustment of the clamping member is needed. The other featuresof the construction and mode of securing to the WallS remain the same as illustrated in Figures l to 3. Y

lt will thus be apparent that a simple,

y compact and efficient device has been providedfor carrying out the Vdesired objects of the invention, and the function and cperation of the improvements Will be readily understood from the foregoing. The structure of the cable supporting means Vadapts the same for ready and convenient adjustment to accommodate the particular size of cable carried thereby; The auxiliary. Wire holding coils are required and made use of as branch Wires 20 are run off'from the main cable or conduit l2. The combined arrangement and construction ofv the cable supporting member and auxiliary wire holding member aifords a means for Vsecuring the parts tothe Wall properly and firmly Without other fastening means of-,any kind, and the described anchoring structure has the advantage of providing a fixed embedded anchorage Which does not disturb or loosen the mortar ofthe Wall vvhen the parts are tightenedduring the clampingr operation as would be the Vcase Where an anchorage was effected Vby the mere action of the screwY alone, Without such a fixed anchoring member. By clamping the body portion 6 of the cable gripping member directly against the exposed end of the plug 24, the said body portion 6 is simply clamped positively between the collar 28 and the outer end of said plug With no appreciable drawing action being effected Vby the tightening of the. screw which would tend to Vloosen the plug inthe mortar'or other material in Which it a pair of' termi'nal fingergportionsV 1 ,acarreo is embedded. The use of the collar provides an effective clamping element for cooperating With the outer end of the plug or sleeve 2a' and also serves to leave the coil 16 out in convenient position for manipulation ofthe Wire Q0 on inserting it into said coil, and furthermore the presence of the collar 28 leaves the terminal of the said coil free to move to form the .opening or passage lS'for said insertion of the Wire.

While l have villustrated and described what regard as the preferred form of construction for embodyingthe improvements, l desire to reserve the right to such changes vor modifications as may fairly fall Within the scope ofthe appended claims.

l'r-aving described the invention, What l claim new and desire to secure by Letters- Patent, is: Y

l. A cable clamping deviceV for fastening cables to Walls and the like, comprising a clamping linemberhaving a Wall engaging portion provided with means for securing thesame to a wall, and cable engaging portions Vcarriedby said lirst portion and comprising a pair of'curved flexible fingers adapted to be spread different distances. apart lengthwise ofthercableY for gripping cables of diferent diameters,` said securing means acting to hold said fingers in springclamping engagement with the cable.

2. A cableclamping device for fastening cables to Walls and the like, comprising a.

single piece of' Wire bent Aupon itself" to Vform a wall engaging portion provided with means for securing the same to a Wall, and p adapted to be spreaddifferent distances apart length- Wise of the cable for gripping cables of different diameters, said-securing means acting to hold said fingers in spring-clamping engagement with the cable. y, Y v ln Witness whereof I hereto afiiX my. signature.
